GitHub本週挖寶TOP 3：免費照片雲盤、遠端幫爸媽修電腦、剪片不掉畫質
今天老陳一步一步講清楚，3 個免費開源神器：自己搭的照片雲盤、開源遠端桌面、無損剪片工具。
第 1 名 Immich —— 自己搭的照片雲盤，Google 相冊平替，人臉、地點自動整理
immich-app/immich
老陳打分 9.0 分。AGPL-3.0 許可。照片多、怕雲盤漲價的人適合，自搭需 Docker。
第 2 名 RustDesk —— 開源遠端桌面，TeamViewer 平替，幫爸媽修電腦、找檔案
rustdesk/rustdesk
老陳打分 8.5 分。AGPL-3.0 許可。普通人直接下載就能用，需對方在電腦前確認，進階自架 Pro 版另收費。
第 3 名 LosslessCut —— 剪片不重新編碼，剪完畫質一點不掉
mifi/lossless-cut
老陳打分 9.0 分。GPL-2.0 許可。剪短影片、去片頭片尾特別快，GitHub 下載免費，商店版為支持開發者收費。
說句實話：三個都免費，但各有門檻：Immich 要自己搭服務；RustDesk 要對方配合確認；LosslessCut 只能剪不能做特效。先看需求再動手。
本片沒有實測，畫面為各項目介紹重新排版，非實機錄屏。
星數：2026-11-01 查詢（Immich 117,828；RustDesk 127,734；LosslessCut 45,537）。

வீடியோவை வெட்ட மணிக்கணக்கில் காத்திருக்கிறீர்களா? LosslessCut நொடிகளில் வெட்டுகிறது. reel வெட்டுவோருக்கு ஏற்றது. எதை வெட்டுவீர்கள், வீடியோவையா அல்லது reel-ஐயா ?

பெரிய வீடியோவை வெட்ட மணிக்கணக்கில் காத்திருக்க வேண்டாம். LosslessCut இலவசமாக நொடிகளில் வெட்டுகிறது, தரம் குறையாது. முதலில் எதைச் சுருக்குவீர்கள்?

LosslessCut GitHub Explained: FFmpeg Stream Copy, Keyframes, and API Automation
lossless-cut by mifi: mifi/lossless-cut
LosslessCut is an Electron desktop application built around FFmpeg stream copying for video, audio, and subtitle media. This overview explains how GOP and keyframe structure shapes cut timing, how Smart Cut selectively re-encodes a short boundary, and how Chromium preview connects to an FFmpeg proxy pipeline for formats the browser cannot play natively. It also covers remuxing between containers, track selection, project files, and the local HTTP API for structured batch workflows. The central trade-off is clear: stream copy preserves source data while keyframe boundaries determine where fully lossless cuts can land.
TimeStamps:
0:00 Stream Copying vs Re-Encoding
1:35 GOPs and Keyframe Cut Timing
2:37 Smart Cut Trade-Offs
3:23 Chromium Preview and Proxy Playback
4:51 Remuxing Containers and Selecting Tracks
6:38 LLC Project Files for Batch Workflows
7:19 Local HTTP API Export Events
7:58 Structured Automation Without the GUI
8:15 GOP Boundaries as the Core Trade-Off
8:56 Source Fidelity and Routing Media Packets
🎞️ Stream-copy editing with FFmpeg
🧩 GOPs, keyframes, and Smart Cut trade-offs
🖥️ Proxy preview for unsupported formats
⚙️ Remuxing, project files, and local API automation
For media workflows, LosslessCut connects familiar timeline decisions to FFmpeg stream copy. The practical concepts to carry forward are GOP boundaries, remuxing, JSON5 project files, and completion-aware HTTP API automation for repeatable batch processing.

LosslessCut: The swiss army knife of lossless video/audio editing (45k stars)
What it does
All text below is quoted directly from the project README.
>LosslessCut aims to be the ultimate cross platform FFmpeg GUI for extremely fast and lossless operations on video, audio, subtitle and other related media files.
Features:
- Lossless cutting of most video and audio formats
- Losslessly cut out parts of video/audio (for cutting away commercials etc.)
- Losslessly rearrange the order of video/audio segments
- Lossless merge/concatenation of arbitrary files (with identical codecs parameters, e.g. from the same camera)
- Lossless multi track/stream editing
- Losslessly remux video/audio into a different container (file) format
- Take full-resolution snapshots from videos in JPEG/PNG format (low or high quality)
- Black scene detection, silent audio detection, and scene change detection
>Everything is extremely fast because it does an almost direct data copy, fueled by the awesome FFmpeg which does all the grunt work.
